LS and LT Radiator and Fan Assembly for 1991-1996 B-Body Impala/Caprice/Roadmaster
Installing the 1991-1996 Impala Radiator (Auto Trans) with Fans solves the common hassle of aligning cooling hardware on a B-Body chassis when swapping in LS or LT engines. It mounts to the original frame rails with OE brackets and retains factory transmission cooler ports so a clean fit requires no adapter plumbing or rail trimming. Precision TIG welded aluminum tanks pair with an oversized core to deliver rapid heat rejection and natural corrosion resistance while keeping overall weight low. Prewired dual electric fans maintain airflow at idle or in city traffic and preserving hose routing with original shroud clearance ensures this assembly serves as a drop in solution.
Precision TIG Welding for Reinforced Aluminum Tanks
The radiator's tanks and core plates are joined using precision TIG welding, which produces smooth, uniform seams that resist leaking under intense vibration and thermal cycling typical of LS and LT swaps. This fusion method avoids common filler contamination, ensuring each joint maintains full material strength and pressure integrity. By relying on premium aluminum for both tanks and core, the assembly achieves natural corrosion resistance and excellent heat transfer without adding unnecessary mass. Every unit undergoes rigorous pressure testing and visual inspection, delivering consistent quality and leak-free performance in demanding driving conditions.
Optimized Dual Electric Fans for Consistent Cooling
Two high-capacity electric fans are prewired to mate directly with the factory harness, eliminating the need for extra relays or splices and simplifying installation. Each fan motor features sealed bearings for long-life operation and draws only enough power to engage when the coolant temperature rises, reducing mechanical load compared with belt-driven alternatives. This arrangement maintains steady airflow at idle and in stop and go traffic, preventing heat soak around the block while keeping noise levels to a minimum. The fans' compact profile also preserves clearance within the factory shroud for a clean under-hood appearance.
Seamless Integration with B Body Frame Rails
Designed specifically for 1991–1996 Impala, Caprice, and Roadmaster automatics, this radiator mounts directly to the original B Body bracket points on the frame rails. Factory transmission cooler ports remain in their stock locations, so there is no cutting of rails or adapter plumbing required to connect cooler lines. Preserving the factory hose routing ensures even coolant distribution through the entire core, eliminating hotspots and promoting consistent temperature control. Development began with a full 3D scan of the chassis to confirm exact fit and minimize installation time for professional and home builders alike.
Tailored Coating Choices for Protection and Appearance
Builders can choose the natural bare aluminum finish to maximize radiant heat rejection and highlight the metal's polished texture, or select the black epoxy coat for enhanced corrosion protection and a stealth look. The epoxy is applied in a two part polyacrylic process that bonds tightly to the aluminum surface and resists flaking during repeated heating cycles. Both finishes receive a clear sealant barrier that prevents oxidation, while the black option includes a UV stable additive to guard against fading in sunlight. These choices allow enthusiasts to balance cooling performance with personal style without compromising core efficiency.
